Profile:

Dianne is convinced that accurate contaminant monitoring is key to effective environmental policy protecting wildlife and human health. Her research documents toxic contaminants in wildlife using the interplay of an organism’s life history, ecology and behavior to evaluate contaminant exposures. Her past work included a ten-year study of the contaminant concentrations and health of the resident harbor seals of San Francisco Bay. Dianne’s graduate research in the Gulf of Maine examined foraging selection in harbor seals and the trophic transfer of mercury from prey fish to seals. As staff biologist to the Penobscot River Mercury Study she designed and ultimately led a multi-year monitoring program which documented mercury concentrations in fish, birds and lobster in the lower Penobscot River and upper Penobscot Bay.

She is presently collaborating with staff from the Penobscot Nation to generate species-specific information on fish mercury concentrations in waters of the Penobscot Nation. For decades, mercury contamination in Maine freshwater fish has denied members of the Penobscot Nation their legally protected sustenance fishing rights. The study, funded by the EPA Environmental Justice Small Grants Program, will identify fishing locations and species that minimize mercury exposure to tribal members, provide a template for contaminant studies in tribal waters across the U.S., and document the need for improvement in federal mercury emissions policy.
